問題1
An LTM device provides load balancing to a web application? The LTM device has two dual-core processors and a licensed SSL Transactions Per Second (TPS) limit of 500 CMP is enabled. TLS connections are used between client systems and virtual servers on the LTM device, as well as from the LTM device to servers used as part of LTM pool. TLS enabled virtual servers utilize certificates based on 2048-bit keys.
During a peak period. 2560 new TLS transactions per second are attempted to the web application via the LTM device.
What will happen in this scenario?

The picture belongs to static content, you can configure static content cache in FS to meet this demand.
An LTM Specialist must configure session persistence for a highly available, highly utilized web- based application.
The following requirements are provided:
- http proxy setup for security persistence information available to
the HA peer in case of failover
- The LTM Specialist needs to minimize additional burden on the LTM
device to the greatest extent possible.
Which persistence profile should be used?

問題9
An LTM Specialist is removing some of the load off an existing cluster by adding a adding a third BIG- IP device to the device group.
The new device can deliver twice the performance of the other two devices.
The LTM Specialist needs to make sure that the BIG-IP device with the highest available capacity is always selected to take over a traffic group in the event of a failover.

問題10
An LTM Specialist upgrades the switching infrastructure and the backend servers on the LAN segments.
The LTM Specialist notices a 20% memory usage increase on the BIG-IP device while handling the same number of concurrent connections.
A comparison of statistics pre-upgrade and post-upgrade shows a significant reduction on the following:
- RTT between the BIG-IP device and the backend servers
- Packet drops in the switch
- Time to First Byte (TTFB)
The LTM Specialist is concerned with the scalability of the number of concurrent connections with the new memory usage.
Which setting should be changed to reduce the memory usage on the BIG-IP device?
